KEEEGIFE JATIUL forming part of Letters Patent No. 681,363, dated August 27, i. 901.

Application filed March 26, 1900. Serial No. 10218. No model.)

To all whom. it may concern.-

Be it known that I, ARTHUR E. Cnsnnnns,

a citizen of the United States, residing at. the I city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have inven l'cd certain new and useful Improvements in Boats, of which the following is a specification.

This invention relates to improvements in boats. I

The objects of the invention are, first, to provide an improved'construction of metallic boat; second, to provide an improved construction of metal boat in which the metal em ployed is not injured, weakened, or hardened by stamping and pressing it into shape, and, third, to provide an improved construction and arrangement of parts in metallic boats which shall insure their buoyancy even when they are capsized. Further objects will delinitely appear inthe detailed description to follow. I accomplish these objects of my invention by the devices and means described in this specification.

'ihe invention is clearly defined and pointed out in the claims.

- A structure embodying my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in

Figure 1 is an invertcd'plan view of a boat embodying the features of my invention. Fig. 2 is a longitudinal sectional elevation taken on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail transverse sectional elevation taken on line 3 3 of Fig. 2. Fig.4 is an cnlarged detail transverse sectional elevation taken on a line corresponding to line 1 4L of Fig. 2. Fig. 5 isan enlarged detail perspective view of a portion of the side of a boat, showing the manner of constructing the same and securing the parts together.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the draw ings, A is the keel of a boat, which is prcfcrably made of a strip of board or planking ot' the form appearing in Fig. 2 and containsa longitudinal groove A.

B are the strips of metal forming the skin or shell of the boat, and C are the ribs. The ribs are secured to a center strip D within the boat, above the keel, and extend outward and are curved to the desired form at the different parts of the boat,

l are the usual bottom boards. The strips of metal 13 are cut to the proper form, so that in forming the boat they are simply curved into position, their width varying at different points to'givc the proper contour to the boat, and their edges are joined by a double seam ll, extending from end to end of the boat, a double scam being formed along the center which is embraced by the keel A on the bottom. The strips of metal, are put in position on the ribs 0, with proper folds for forming the seams, and as each strip is put in position it is secured to the ribs by suitable nails, screws, or other means, as a, thcprefer'rcd fastening beluga clenched nail. The folded portion is turned outwardly, as at u, so that the nail can be driven entirely under the seam. The second piece, which is properly folded to embrace this scam, is then put in position, and the seam i3 is roll-ed down' tight. This seaming forms a perfectly-tight jointin the metal and also gives the boat added strength and rigidity, making it possible to make a very light boat by using thin steel, the'structu re being found to be very cll'ective, owing to the fact that the metal plates are in nowise injured.

It is found that it is not necessary to do more than fold the seams iii-position, but of course those seam-joints might be soldered as an extra precaution where desired. The

scam folds down securely over the fastener u, so that no leak over occurs at this point. i linish the upper edge of the boat by folding the top strip, at each side upon itself, as at I, (see Fig. 4,) and then place rails c c-on either side of the fold and secure them in position by suitable rivets or bolts n.

in each end of the boat, entirely indcpend vention.

cut of the shell, I place water-tight chambers F F, the same being secured under seats G G but otherwise they are disconnected from the shell of the boat to serve as airchambers to insure the buoyancy of the boat even though it is capsized or otherwise filled with water.

Having thus described my improved boat, I desire to state that it can be greatly varied in its details without departing from my inlhe strips of metal B might be seamed together and secured to the framework by other means than I have shown. While the gunwale of the boat as I have produced it is a satisfactory and suflicient construction, I am aware that it could be finished in diiierent ways and still be effective and satisfactory. Other styles of keel might be formed than that which I have here shown. In certain forms of the boatuo keel,'of course, would be required.

I have particularly illustrated double seaming for joining the longitudinal strips of metal together in this boat, but beg to remark that a simple seam will be found to be very cilicient and satisfactory, although the double seam is safer and of course adds more to the rigidity of the shell.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a boat, the combination of the center strip D; ribs C; a skin made up of strips of sheet metal extending longitudinally of the boat, varied in width to give the proper contour to the boat and having their edges joined together by a double seam, and secured to the ribs by suitable clench-nails embraced underneath the seam; and a suitable keel grooved to embrace the center seam of the boat, as specified.

2. In a boat, the combination of a framework; the skin or shell made up of longitudinal strips of sheet metal suitably conformed to the boat, the edges of which are joined by a double seam, suitable fasteners connecting the skin and frameworkhvhich are embraced by the seams.

3. In a boat, the combination of a sheetmetal shell or skin, the upper edge of which is folded on itself and retained between suitable rails e, e, as specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
